FAQs
The 85100E145SZ50 is designed for standard Souriau 851-series mating connectors with a backnut backshell and 1/3 bayonet coupling. It uses a 5-cavity layout and delivers with connector, making it suitable for aerospace, defense, and industrial automation harnesses. Verify mating pair compatibility by matching the 851-series code and layout to ensure proper pinout and clearance in your panel.
MIL-DTL-26482 SI qualification confirms compatibility with MIL-spec interface requirements and enhanced signal integrity under vibration and temperature cycling. For your program, this reduces risk during environmental testing, shortens qualification timelines, and supports reliable operation in aerospace and rugged industrial equipment.
Yes. With an aluminium shell, cadmium plating, backnut backshell, 1/3 bayonet coupling, and a 5-contact solder cup arrangement, the receptacle is optimized for high-vibration aerospace and defense harnesses. It supports Z orientation and a compact footprint, simplifying routing in aircraft panels and military vehicles while maintaining secure, compliant connections.
Maintenance considerations include ensuring mating interfaces are clean and free from contaminants prior to engagement, using proper torque on mounting hardware, and verifying continuity after installation. The 85100E145SZ50’s backnut backshell and bayonet coupling help minimize wear during repeated mating cycles, while the cadmium plating provides ongoing corrosion resistance in challenging environments.
Key specs include 32.7 mm length, 28.9 mm width, 28.9 mm height, 20.2 g weight, 5 contacts (socket/female), cadmium plating, aluminium shell, 1/3 bayonet coupling, backnut backshell, and operating range -40 to 125 °C. It is REACH compliant and designed for square flange receptacle configurations, with a Z orientation for harness routing and delivered-with-connector compatibility.
